Abstract: 1,248,419. Liquefied gas storage containers. MOTHERWELL BRIDGE ENG. Ltd. 9 Dec., 1969 [9 Dec., 1968], No. 58448/68. Heading F4P. In an insulated liquefied gas storage container comprising an outer shell 1 and an inner tank 2, boil-off gas from the inner tank is passed through the insulating layer before reaching the container outlet 10 to minimize external heat leakage. The insulating layer is situated between two walls 3A and 4 in the space between the tanks and on the roof 3 of the inner tank, the roof insulation being covered by a gas-tight sheet 8 communicating via a pipe 9 with the outlet 10. Boil-off gas from the tank enters a space 20 between wall 3A and the inner tank, passes through the insulating layer to an outer space 21 and then via passages 5 and a pipe 6 to the outlet 10. Outlets 7 in the inner roof 3 allow boil-off gas to reach the outlet through the roof insulation. Valves 11 in the outlet control the proportions of gas escaping via the roof and side wall insulation. In other embodiments the outer space 21, or both spaces 20, 21, are replaced by porous or perforated non-porous pipes which conduct the gas through the insulating layer at the side walls. Gas warmed by passage through the insulating layer may be used to heat the base of the container to prevent freezing. The inner tank may be strengthened by internal ribs or stiffeners.

Title: Branch connections to pipes
IPC: F16L41/06
Filed: 1980-01-16
Abstract: A machine for drilling and tapping and then fixing a ferrule in a main pipe 1 while the pipe is carrying fluid such as water under pressure and to which pipe the machine is clamped has a valve body 5 open at the bottom to the pipe 1. A ball-shaped valve member 11 within the body 5 has a passage 12 through which a drilling and tapping bit 34 is passed to make a tapped hole in the pipe 1. The bit 34 is carried by a spindle 25 rotatable in a spindle carrier 6 detachably mounted on the valve body 5. After the tapped hole has been made the bit 34 is withdrawn above the valve member 11 which is then closed. The spindle carrier 6 is separated from the valve body, the bit 34 replaced by an adaptor carrying a ferrule and the spindle carrier 6 re-engaged with the body 5. The valve member 11 is then opened and the ferrule is passed by the machine through the passage 12 and screwed into the tapped hole. A drain outlet 21 open to the passage 12 allows water to escape to waste when the valve is open carrying with it swarf that would otherwise drop into the main as it is being drilled and tapped. The drain outlet 21 also serves to reduce fluid pressure with the machine so that the design specification for strength can be reduced. In a modification a flexible gasket is inserted between the valve body 5 and the pipe. The gasket can conform to a range of pipe sizes.   <IMAGE>
